that just passed here. this was a key area, an area where a lot of law enforcement was gathering. we saw a truck. there were armed personnel on it. we saw bomb sniffing dogs from the fbi. really, the impression was they were searching for an ied. something you would see in a theater of war, in a combat zone, not here in the streets of boston. you still have a lot of personnel. some have slowly been pulling back. again, it's a very active scene that's going on right now. we don't know the status. we don't know where this individual is, whether he's close. whether he's in custody. but by creating a huge perimeter around this particular area, what they do hope to do is either flush him out, or at least tighten the noose. and so that's what they're trying to do. they are going door-to-door. they are canvassing different homes, they are trying to do a sweep. remember, these people, even though they were on the run, they hijacked -- they basically harnlg acked an individual and then they fled and they were still throwing out bombs we're told either bombs or grenades or some sort of pipe bomb.
